How to understand your genetic clock and how it moves

For many years, it was believed that cells were immortal when placed in an ideal environment. This belief was abandoned in the early 1960s, when Leonard Hayflick, Ph.D., noticed that human fibroblasts in tissue culture divide on average no more than 50 times. Hayflick found that if cells were frozen after 20 divisions, they "remember" that after thawing they had 30 divisions left.

The researchers also noticed that fibroblasts become old in appearance, approaching 50 cell divisions. They get larger and accumulate an increased amount of lipofuscin, the pigment responsible for age spots. Based on Hayflick's findings, experts have suggested that there is a genetic clock in every cell that determines the onset of old age.

Currently, many researchers in this field are working with the so-called telomere shortening theory of aging. Telomeres are the ends of DNA. With each cell reproduction, a small segment of DNA is removed from the telomere, and the shorter the telomere becomes, the more gene expression is damaged. The result is cell aging.

In addition to serving as the “clock of aging,” telomeres are involved in protecting the ends of the chromosome from damage by controlling gene expression, and also contributing to chromosome organization. Telomere not only determines cell aging, but also the risk of cell overgrowth into cancer, Alzheimer's disease and other degenerative diseases.

Slow down the clock

The key to increasing human lifespan will ultimately be associated with maintaining or restoring telomere length in DNA. But this technology will not be available to us for decades. Fortunately, there are old ways to slow down our genetic clock right now, which are:

• Stress management
• Regular gymnastics
• Sleep at least 8 hours a day
• Maintaining ideal body weight
• A diet rich in vegetables and fruits
• Preference for foods with a low glycemic index
• Daily intake
• Taking the optimal amount
• Supplemental intake of polyphenols, and other essential nutrients.

Careful consideration

Research has shown that many nutrients help fight telomere shortening, especially B vitamins such as, and; ; ; and and. The best way to ensure you are getting all of these and other nutrients is to take a high quality multivitamin / multimineral supplement. Should you take iron as part of a multimineral? If there is no significant need for iron, or you are not a menstruating woman, iron supplements should be avoided. Telomere shortening has been linked to iron intake. Excess iron can also trigger an increase in free radical activity.

Supplementation is also a good idea - most experts recommend a minimum of 2,000 IU daily. In one study, researchers examined the effects of vitamin D on telomere length in white blood cells of 2,160 women aged 18-79. The higher their vitamin D levels, the longer their telomeres were.

In terms of aging and telomere length, there was a five-year difference between those with the highest vitamin D levels and those with the lowest. Obesity, smoking, and lack of physical activity can shorten telomere length, but researchers found that increased vitamin D levels counteracted these effects. This 5-year difference means that a 70-year-old woman with a higher vitamin D level has a biological age of 65.

Fish oil also goes a long way in slowing down the genetic clock. Higher levels of EPA and DHA omega-3 fatty acids have been shown to inhibit telomere shortening in long-term studies. The recommended fish oil dosage is based on providing a daily intake of 1000 mg EPA and DHA.

Finally, the flavonoids and polyphenols of grape seed, pine bark (Pycnogenol) and green tea not only reduce inflammation but also prevent telomere shortening in experimental studies. The recommended dosage for extracts providing at least 90 percent of the polyphenols is 150-300 mg per day.

Insulin approach

But perhaps the biggest cause of premature telomere shortening in North America is the insulin hormone immunity that occurs in obesity, prediabetes, and type 2 diabetes. As recent studies have shown, insulin resistance is associated with shorter telomeres. Achieving ideal body weight and employing strategies to increase the sensitivity of your cells to insulin are critical goals for preventing telomere shortening.

Goals:

1) to acquaint children with the new value, to form an idea of ​​the units of time: hour, minute4
2) improve computational skills, the ability to solve problems;
3) develop the ability to observe, compare, draw conclusions;
4) foster interest in a math lesson, teach to value time.

Teaching methods: verbal, visual, problematic, reproductive.

Equipment: a watch model for each student, Znayka, Mathematician, an alarm clock, a stopwatch, an hourglass, an electronic clock, a mechanical clock, a sheet with a riddle.

During the classes

I Organizational moment.

- Let's all stand. Let's calm down. We sit down quietly.
- Today we have guests at the lesson who came to see how you can solve problems and examples.

II Message of the topic of the lesson.

The long-awaited call is given -
Lesson begins!
Here are ideas and tasks,
Games, jokes, everything for you!
We wish you good luck -
Get to work, good hour!

- The topic of our lesson is encrypted. Look closely at the board.

There is a row of numbers on the board, with a letter under each number. To learn the topic of our lesson, you need to arrange the numbers in ascending order (that is, from the smallest to the largest number).

- Well done! The topic of our lesson is “Hour. Minute." (I post the topic on the board.)

III Oral account.

- At the beginning of the lesson, we will count orally.
- 2 students go to the board, solve examples of the form:

7 = 27
+9 = 59
35 – = 30
77 – = 70
49 + 1 =
89 + 1 =

- While the guys are working at the blackboard, we will solve problems and examples orally:

- The first term is 10, the second is 8. What is the sum?
- Decreased 77, subtracted 7. What is the difference?
“I’m thinking of a number, if you subtract 1 from it, you get 99. What number am I thinking?” (100)
“I’m thinking of a number, if you add 60 to it, you get 63. What number am I thinking?” (3)
- In the number of 100 sk-ko dess? units (10 dess. 0 units)
- In the number 84, sk-ko des, units? 45? 39?
- In the number of 5des 6 units? What is this number? 7d 1 unit? 2d. 8 units

2) The game "Silence".

- Well done! And now the tasks:

3) Uncle Fedor wrote 15 letters to mom and dad in Crimea, and 5 more letters in Prostokvashino. How many letters did Uncle Fyodor write to Prostokvashino? (twenty)

- How did you know?
- Chicken Ryaba laid 100 simple eggs in a year, and there are 20 fewer golden eggs. How many golden eggs did Ryaba Chicken lay? (80) -
- Well done! Coped with the task. Now let's check the students who worked at the blackboard.

IV Work on the topic of the lesson.

- Look, Znayka Mathematician is our guest again. - What did he bring us? (Alarm.)
- And some other piece of paper with a note. Let's listen to what is written here.

Two sisters one after another
Run round and round.
Shorty just once
The one higher every hour.

W. What is it all about?

D. About the hands of the clock.

W. What is this shorty running in a circle?

D. Hour hand.

W. Why does her taller sister run faster?

D. Minute hand.

W. How does the hour hand move?

D. from one digit to the next. From one big dash to another big dash.

W. What happens to the minute hand?

W. How does it move?

D. From one little dash to another little dash.

W. How many such dashes are there on the dial? Count.

D.(5 minutes and 5 minutes - there will be 10 minutes, 10 minutes and 5 minutes - there will be 15 minutes, and even 5 minutes - there will be 20 minutes ... ..), 60 minutes will pass.

W. The distance from one small dash to another small dash is called….

D. Minute.

W. And the whole circle that she goes through….

D. Hour.

W. So how many minutes are there in an hour? (60)

(I post a poster on the board: 1h. 60min.)

W. Look how Znayka Mathematician smiles. (I post the drawing). He wants to say that you are great. Themselves figured out the new topic.

W. Test yourself by reading the & tutorial on page 27, open it.

W. How many minutes are there in 1 hour?

W. How does the hour hand move?

W. How does the minute hand move?

V Physical education.

Are you tired?
Well, then everyone stood up in unison.
We will sink our feet
We'll clap our hands

Shake our head tick-tock, tick-tock
We raise our hands
We put our handles down
Let's sit down!

W. And now we open the notebook, today is October 2, class work, write down the topic of the lesson.

W. And now we have prepared the watch models.

- What time does the watch show if the hour hand points to the number 9 and the minute hand points to the number 12? (Show.)
- The clock is exactly 12 o'clock (11 o'clock, 6 o'clock), but how will the hands be located in an hour?

W. Guys, what's this in my hand? (Stopwatch.)

W. In order for you to get a concrete idea of ​​the duration of one minute, at my signal you must start and finish writing numbers in a row, starting from one.

After a minute, the teacher finds out who managed to write down the numbers and how many.

W. Now count the numbers, starting from 21, pronouncing two-digit numbers in a whisper - 21, 22 ...

W. Concludes: in 1 min. You can read 60–70 words, name numbers from 21 to 81, solve 15–20 examples.

A minute is not a small unit of time at all, if used wisely.

W. And how do you understand the meaning of this proverb:

“A minute saves an hour”.

W. US. 27 orally solve N 2.

W. Now let's work on the tasks, p. 27 N 4.

W. Read the problem carefully. Where were the tickets purchased? What are the two main words we will single out for solving this problem?

D. Film and theater.

W. Do we know how many movie tickets were bought?

D. Yes. 7.

W. Do we know how many tickets were bought for the theater?

D. Yes. 5.

W. Do we know how many tickets we bought in total?

D. No.

W. Is the short entry finished? What is missing?

D. Curly braces and question mark.

W. Let's solve the problem at the blackboard.

7 + 5 = 12 (b.)

Answer: 12 tickets.

Examination:

- What does the number 7 mean? (Tickets purchased at the cinema.)
- What does the number 5 mean? (tickets purchased for the theater.)
- What does the number 12 mean? (Total tickets.)

W. How did you know how many tickets you bought in total?

D. I am to 7 + 5.

W. Well done! Appreciate.

W. Create the inverse problem.

D. Bought 12 tickets. Of these, 7 tickets to the cinema, and the rest to the theater. How many theater tickets did you buy?

W. Shows cr. writing at the blackboard for the task, and the children help him.

W. The solution is written down by 2 students, and the children write down the solution in a notebook.

12 - 7 = 5 (b.)

Answer: I bought 5 tickets to the theater.

Examination:

- What does the number 12 mean? (Total tickets purchased.)
- What does the number 7 mean? (Tickets purchased at the cinema.)
- What does the number 5 mean? (Tickets purchased for the theater.)

W. How did you know?

D. I subtracted (ate) 7 from 12 and got 5.

W. Well done! Appreciate.

W. You will compose the inverse problem at home and solve it.

VI Physical culture minute.

Tick ​​tock, tick tock
Who knows how to do this in the house?
This is a pendulum in a clock
Beats every beat.

(Tilts left and right.)

And the cuckoo sits in the clock,
She has her own hut.

(Children sit in a deep squat.)

Time will bite the bird
Hiding behind the door again

(Squats.)

The arrows move in a circle.
Don't touch each other.

(Rotation of the trunk to the right.)

We will turn with you
Counterclockwise.

(Rotation of the trunk to the left.)

And the clock goes, goes

(Walking in place.)

Sometimes they suddenly lag behind.

(Slowing down the pace of walking.)

And it happens that they are in a hurry
As if they want to run away!

(Running in place.)

If they are not turned on,
Then they get up completely.

(The children stop.)

The game is over
It's time for us to sit down at our desks.

VII Consolidation of the passed.

W. Guys, the clock did not always have such a familiar look for us as it is now. Previously, the time was determined by the sun and was called a sundial, later the Egyptians invented a water clock, then an hourglass, which is still used in medicine to determine the period of time allotted for a particular procedure. Currently, there are different types of clocks - from mechanical to electronic.

W. Now there will be a task like this, row 1 solves examples for an hourglass, row 2 for electronic, row 3 for mechanical. Let's see which row will cope with the task faster.

- Decide.
- When the students have solved the examples, we check.
- Let's check.
- 3 students at the blackboard sign the answers over the examples written in advance by the teacher.
- If there are mistakes in the examples, we correct them.
- Well done! We also coped with this task.

VIII Outcome.

- And now we will summarize our lesson.

W. What did we do in class today?

D. We solved problems and examples, got acquainted with the units of time.

W. What kind of problems did we solve?

D. Inverse tasks

W. What units of time have you met today? (Hour. Minute.)

W. Why is the minute called? (Because it passes the distance from one small. Dash to another.)

W. Why an hour? (Because she goes all the way.)

W. Your answers showed that the lesson you learned is not bad and has reached its goal.

IX Grading.

- To whom I gave grades during the lesson, during the break, I will put them in your diary.
- Thank you for the lesson.

X Homework.

- С.27, N4 (3); N3 (1, 2, 3).

XI Organizational completion of the lesson.

- And now we all get up. The lesson is over.

MOU Gymnasium №25

"A minute saves an hour!"

Extracurricular activity for students in grades 3-5

Tolmacheva T.N.

Irkutsk 2009

Location: assembly hall of the MOU Gymnasium №25.

Goals:

the formation of the ability to plan your day;

introduce children to the types of clocks;

development of the ability to analyze, draw conclusions, generalize;

fostering a respect for time by various means (for example: musical, cinema - arts, etc.)

Equipment: projector, screen, laptop, presentation, video fragments, texts with assignments for groups, metronome, felt-tip pens, A4 sheets, bench, alarm clock, blanket, books, bag, medical gown.

Extracurricular activity progress

entrance to the assembly hall: "Morning" (from TV "Office Romance").

1. Teacher: Good afternoon, dear guests, colleagues, guys. I am very glad to see all of you. No one will argue with the fact that the past minute will never return to us. Today we will talk about the most valuable thing that helps a person in life - about time, and the theme sounds like this: "A minute saves an hour!" (slide 1).

– What is time, what do you think? Yes, you can talk about time for a very long time. This is the change of seasons, this is our age - today you are 9, 10 and you will not notice how quickly time flies by and it will be 20. And in the shortest definition we can say that time is our past, present and future.

2. - (Slide2) What is the name of this device and what is it intended for? (show metronome). The metronome measures even beats (tempo).

Let's move in time with the metronome. Now we live in the same rhythm! Well done!

And the rhythm both in life for each person and in music is different (Video-fragment1).

3. In the cartoon you all know (slide 3), the length of the boa constrictor was measured in different ways, but most of all the boa constrictor himself liked to measure himself in Parrots - there were 38 of them.

- A how is time measured? (slide 4) Answers of children.

in hours - one hour after another (they even named the device that measures the time); - Teacher: What else?

inside an hour - minutes (there are 60 of them), inside each minute - seconds (also 60);

hours add up to "day and night - day away"; - Why do they say so?

Teacher:

day by day and week by week - month;

12 months - in a whole year;

year after year - into the century;

centuries - in an era (1000th anniversary) ...

4. People value time, and they determine it by the clock. Different clocks were used in different eras. And about their varieties, a student of the 7th grade Borisova Liza has prepared a presentation for you (Video - fragment 2).

What else do you know?

5. TASK: And what clock is used to measure time in this fairy tale, if this fairy tale is musical.

Hearing: ( Scene "Midnight" from the ballet "Cinderella" by S. Prokofiev) After the answer (slide 5)

6. The value of time has now increased significantly. Even Americans often say: “Time is more valuable than money” (slide 6).

Why? (children's answers). After all, the lost can be earned again, but the wasted time cannot be returned. Many good deeds can be done during every minute spent.

7. And now let's see what happens to people who are wasting their time (Video-fragment3) "The Tale of Lost Time" - the moment of transformation.

What is the name of this tale? And who has not seen, be sure to take a look.

Have you heard this expression: (slide 7) "Precision is the courtesy of kings"? How do you understand this? Try to use these words.

Do not abuse other people's time and do not waste yours.

8. What is the secret here, that someone has time everywhere - and at school they study well, and attend various circles, and go to bed on time, but someone does not - after all, there is one time for everyone ?!

And the secret is simple! In the ability to plan your time. A student of grade 9 Belyanina Anna will tell you about the daily routine. (Slide 8)

Daily regime:

At 7.00 - rise

From 7.00 to 7.30 - Make your bed, do morning exercises, wash, dress, comb

From 7.30 to 7.50 - have breakfast

From 8 am to 8.30 am - spend half an hour outdoors before sitting down for lessons

From 8.30 to 11.30 - do your homework

11.30 to 12.00 - lunch

After lunch, take your time to go to school to get some fresh air, then you will be cheerful and attentive. Returning from school, also go slowly.

After dinner with your family, you have time to help your mom with the housework and read a book.

Go to bed at 10 o'clock in the evening. Not later! Everyone needs to get enough sleep, especially those who are in school.

(Slide9) The main thing:

Go to bed and get up on time.

Do gymnastics in the morning.

Temper yourself.

Strictly follow the daily routine.

Do sports in your free time.

Teacher: (Slide 10) German writer I. Goethe said: Order teaches us to save time. Do you save your time?

9. But how our ancestors valued time, they say proverbs and sayings.

Group work.

I propose to create 2 groups.

Assignment: Who will remember more proverbs and sayings about time (one tells).

Group work report.

The rest at this time listen and sing along with the performer V. Shainsky's song "While the clock is knocking." What is this song about? (Slides 11,12,13). Cover the projector with a piece of paper.

10. And now, the 11th grade student Lera Chebotareva will introduce you to ways to save time.

Physical education:

To make it easier to get up in the morning

You need to put everything in your bag.

In the evening - notebooks, pens - everything is in order!

Go to bed - do not rush

Write down a plan for tomorrow.

If you start the day by charging,

So everything will be all right

(Slide14) Time - don't waste your time!

Take your time!

11. TASK: Sometimes, finding yourself without a watch, falling asleep and waking up in cloudy weather, you look out the window - and you cannot understand: day, morning or evening-night outside. Music is another matter!

What time of day is it?

"Morning" is a work by E. Grieg, a composer from Norway.

Hearing (fragment). After answering(Slide15)

12. ASSIGNMENT: (Slide16) And the morning of our whole country begins the main song of the state. What is it called? (Hymn), remind the first line: (Children's answers) Close the projector.

13. Scene “Who Stole Egorka's Time”.

will allow you to check the validity of all the above words:

Student ... We know time is stretchable

It depends on

What kind of content

You fill it up.

He has stagnation

And sometimes it flows

Unloaded, empty,

Hours and days are in vain.

Let the intervals be uniform,

That our days are divided

But putting them on the scales

We find long minutes

And very brief hours.

4 girls, 4 boys. Boy1... Once upon a time there was an ordinary student, whose name was Yegorka.

Girl1. Our Yegorka is crying bitterly.

Girl2... Our Egorka is dissatisfied.

Boy2. To do my homework, I won't have a day.

Girl 3. It would be a day for at least a week ...

Boy3... ... Then it would be another matter. Friends would not laugh

Then I would have done everything myself.

Girl4... Did the floor sweep?

Girl1... Did you wash the dishes?

Boy4... I would make the bed myself ...

Boy1... I would go to school myself.

Girl3... I drank coffee - did not burn.

Girl4... Because of the haste, for example, I would not solve the example a hundred times.

Boy2. I would ride on the hill ...

Girl1... Yegorka would have lived well.

Boy3... Well, even though the day would be one hour longer with us ...

Girl3... ... I would put on the boots myself.

Boy4... I would also lace up, not my grandmother.

It’s not difficult for me, I can, only time ashore.

Well, at least for a minute, there were longer days.

I would be no worse than you, I would not be late for class.

(Lies down.)

Girl4... We agree with this without dispute, Yegor is missing a day.

Girl1... Didn't finish so many cases!

Girl2... Well, where is he doing time?

Girl3... Look, Yegorka woke up.

(Yegorka is jumping on one leg, looking for something.)

Girl4... For half an hour I could not find a lost sock.

Boy1. They are never there!

Girl1... Doesn't put socks back in place.

Girl 2. Finally I found a sock.

Boy2... Where is the belt?

Girl3... In search, he knocked off his feet.

Girl4... Our Egor was looking for notebooks.

Girl1... I played hide and seek with him.

Girl2... And, what a game here, it's time for him to run to class.

(Yegorka runs away.)

Girl 3. Here, grabbing a book under my arm.

Our Egor is skipping.

Girl 4. Suddenly back. (Egorka returns.)

Boy 3. (Crying.) I didn't take the pencil case, I was late for school again.

(Yegorka leaves.)

Girl1. Let Yegorka roar bitterly.

Denvochka2... We don't feel sorry for him at all.

Girl3... The thief did not go to Egor.

Girls (together). Time was stolen by Egor himself. (Everyone leaves.)

Who keeps track of the minutes

Time won't let it down

Who saves time.

Who knows how to live by the clock

And appreciates every hour

That is not necessary in the morning

Wake up ten times.

And he won't speak

Why is he too lazy to get up,

Do the exercises, wash your hands

And make the bed.

He will have time to get dressed on time,

Wash and eat

And before the bell rings

To sit at the school desk.

Friendship is good with a watch,

Work, rest

Do your homework slowly

And don't forget the books.

So that in the evening, going to bed,

When the time comes

You could confidently say:

"It was a good day."

14. (Slides 17-23),Song"Bells"

It is very important in life to have time to notice the beauty around you.

15. -Let's summarize our meeting together.

- (Slide 24) Your task is to guess what word is hidden in the picture !?

Time will tell us

About everything in the world.

About snow-white (clouds)

O (Sun) and about summer

About how stormy ( river)

Into the rocky (Coast) beats

(Slide 25) As viewed (the mountains) downright,

(road) twists like a ribbon ...

(Wedge) the crane flies away

And on the hand (snowflakes) melt.

(Slide 26) About how yellow (sheet) circling

And the light in (window) burns all night.

As they go out in the morning (lights),

Go to sea (ships)…

Like u (bonfire) friends are singing

(Slide 27) And in the meadows (flowers) bloom ...

How the pages rustle (books),

How dear in life every moment!

Music: "Fear7SeaOfTime" cRoyalHunt

Notice (listen, compose, play, sing)

and you will become a wonderful person living on Earth!

(Slide 28) But even if you do not hear the voice of the clock -

time is running out anyway. Don't lose it!

Appreciate every minute so that, as an adult, you do not regret wasted time.

Well, the time of our meeting has come to an end (slide 29) but hours go on and life goes on.

Until next time!

To the question of an essay on the topic is the proverb true that a minute saves an hour given by the author Elena Naimova the best answer is If you miss a minute, you will lose an hour. Know the price of the minutes, and the count of seconds
Lost thing can be found, lost time never
Learn to respect every minute and make good use of your free time.
__
Free topic "About free time, hobbies" - essay "What I like to do in my free time"
When lessons end, weekend or vacation comes, I never have a question: what to do so as not to get bored? My day is usually scheduled by the minute, and I am only glad of this, because I manage to do a lot of interesting and useful things.
I have been studying English since I was four, and now I am studying with a teacher three times a week. I am sure that a good knowledge of a foreign language will definitely come in handy in the future.
And I also attend the karate section with a friend. There we not only master the techniques of self-defense, but also learn to control ourselves in difficult situations, develop our own strength and agility.
In the evenings I like to play computer games. I have a computer at home, in addition, my friends and I often go to the computer club to play together.
It seems to me that good friends and interesting things are reliable protectors against boredom and discouragement.
In Russian schools, students have vacations four times a year. The academic year is divided into four quarters. The fall and spring breaks are very short. Both those and others last only 7 days. But my classmates and I have enough time to go somewhere and have a good time. We usually go to a holiday home or another city to change the environment.
The winter vacation lasts two weeks. At this time, it is good to skate and ski and play hockey. During the winter holidays, I like to go to the cinema and theater, museums, art galleries and concert halls.
Summer holidays are the longest. They last for three months. In the summer I have so much free time that I can do a lot. - I can relax outside the city, go on excursions and travel.
Sometimes in the summer my parents and I go on a long journey. And We visit ancient Russian cities or travel by ship. I really love to sail on ships. Usually we go to Astrakhan by train, and then sail to Moscow by ship. He drops anchor in every city. We go ashore and go on an excursion for an hour or two. We visit the sights, and we have the opportunity to learn more about the history of this or that city or place.
But mainly we spend summer vacations outside the city. In my opinion, there is nothing better than Russian nature. We have a small country house in a very picturesque place not far from Zagorsk. There is a river and a lake. My friends and I often swim there and go boating. I also love to sunbathe.
There are a lot of fish in the lake, so sometimes I go fishing. I like to sit in silence, wait for a fish to come across, and listen to the birds singing in the trees. When I manage to catch a fish, I immediately release it, because I fish just for fun.
When it's very hot, I usually go to the forest. The air is cool and fresh there. I like to walk in the shade of trees and pick mushrooms and berries. I have a dog named Jack.
He is very happy when I take him with me to the forest. Jack loves chasing butterflies and dragonflies. Sometimes I play with him. I throw the stick at him and he brings it back to me.
But last summer my parents decided to go somewhere else for a change. They decided to go to Crimea. I think this was the biggest mistake they ever made. Here's what happened in a nutshell.
For starters, it was very difficult to find where to stay. We rented a room in a house far from the sea. This was the only place we managed to get. The road to the beach took us about half an hour. But as it turned out a few days later, it didn't matter

Class hour on the topic:

"A minute saves an hour."

6 "A" class. year 2013.

Tasks:

1.To teach children to deliberately and appropriately allocate their time

2. Teach to save your own and other people's time.

3. To deepen the knowledge of students about the need for rational use of their time.

On the blackboard proverbs and sayings:

The biggest waste is a waste of time.

Time is more precious than money.

Time will teach everything.

Time to ruin - not to turn back.

Everything has its time.

Where labor is, there is happiness.

Time is behind us, time is in front of us, but with us it is not.

Teacher: Guys, you already guessed that today we are going to talk about time. What do you think is the point in the proverb: "Know the price for the minutes, and the count for the seconds"? (Students speak up).

Output: TIME IS NECESSARY.

If a person is educated and intelligent, he knows how to save his own and other people's time. Because he has a lot to do in life.

And such a person calculates everything in minutes. Such a person is said to be accurate and punctual. He always keeps his promises, he is never late for anything. Being one minute late is already a "crime." Save your time. Save someone else's time. Be precise and organized, neat and disciplined!

Teacher: We must remember the sage's sayings: "Time is the fabric from which life is woven."

How many years should a person live? Scientists say that the average is not less than 100. Why is human life expectancy 2-3 times less? There are many reasons. And one of them is the inability to choose the right profession, to determine the path of life, taking into account their inclinations and abilities. As a result, the profession is mastered slowly and late, and not everyone in it achieves mastery. Hence, dissatisfaction and various diseases.

Human capabilities are great. Much can be achieved as a result of systematic, purposeful, organized work. However, studies have shown that even talented people often achieve little if they don’t know how to value time. Conversely, many people, even those who do not have outstanding abilities, manage to achieve great

success in life, if they take care of time, properly organize their work, their lives.

Many people waste their precious time. They live as it happens, going with the flow, lead a hectic life, do not use their capabilities and abilities, and postpone many important things for the future. It was not by chance that the Roman philosopher Seneca remarked: "As long as we are going to live, life passes."

The main reason why precious time is lost is disorganization, excessive fuss, inability to plan your work, to build your life correctly.

It is necessary to learn to take care of your own and other people's time already at school, since these are years of not only learning, but also the formation of a personality, preparation for future life

Leading: We open our oral journal "A minute saves the hour". The first page of the magazine is entitled “Price of a minute”.

The value of time has now increased significantly as the flow of information has increased. It is not for nothing that Americans often use the expression "Time is money." However, today we hear more and more often: time is more valuable than money. In a sense, this is true: well, a person has lost, or a certain amount has been stolen from him, of course, he is offended, but what he has lost can be earned again. But the wasted, wasted time cannot be returned.

There is a very instructive poem on the page of our magazine. Let's listen to him. Readers come out and tell (read) one quatrain.

1. Keep hours counting seconds,

They keep track of the minutes.

The watch won't let you down

Who saves time.

2 who knows how to live by the clock

And appreciates every hour

That is not necessary in the morning

Wake up ten times.

3. And he will not speak,

Why is he too lazy to get up,

Do the exercises, wash your hands

And make the bed.

4. He will have time to get dressed on time,

Wash and eat

And before the bell rings

To sit at the school desk.

5.With watch, friendship is good!

Work, rest

Do your homework slowly

And don't forget the books.

6. So that in the evening, going to bed,

When the time comes.

You could confidently say:

"It was a good day!"

1. Keep hours counting seconds,

They keep track of the minutes.

The watch won't let you down

Who saves time.

Leading: Time is precious to people, and they determine it by the clock. They used different clocks in different eras.

How did it all begin?

1. The very first hours on earth are solar. They were very simple: a pole stuck in the ground. A timeline is drawn around it. The shadow from the pole, moving along it, showed what time it was now.

The sundial had one significant drawback: it could only "walk" on the street, and even then on the sunlit side. This, of course, was extremely inconvenient.

2. Apparently, that's why the water clock was invented. Droplets of water flowed from one vessel to another, and by how much water flowed out, they determined how much time had passed. For many hundreds of years, such a clock has served people. In China, for example, they were used more than 4 thousand years ago. By the way, the first alarm clock on earth was also a water alarm - both an alarm clock and a school bell at the same time.

Sometimes they say: "A lot of water has flowed under the bridge since then," and we understand that a lot of time has passed.

3. The hourglass was arranged like a water clock. The hourglass consists of two small cone-shaped vessels connected by their tops to each other, with a narrow opening at the junction of the vessels. The upper vessel contains sand, which seeps through the hole in a thin stream into the lower vessel. When all the sand from the upper vessel is in the lower one, a certain time elapses, for example, one minute.

Sometimes the time is determined by the striking of the clock. Hence the old expression "a beaten hour".

Time cannot be killed, that is, it must not be wasted. It is important to develop a sense of time in yourself, to learn to save every minute.

Have you heard of the flower clock?

In the morning, on a sunny meadow where dandelions grow, you can find out the time without a wristwatch. Dandelions open up together at five o'clock in the morning, and by two or three o'clock in the afternoon they extinguish their golden lanterns. Listen to a poem about dandelions.

By the river is a green meadow,

Dandelions all around

We washed ourselves with dews,

Amicably opened a little.

How the lanterns burn

They say to you and me:

"It's exactly five o'clock,

You can still sleep! "

Dandelions are meadow clocks.

But the water lilies are a river clock. No wonder they are called "tourist watches". At seven o'clock in the morning, they open their snow-white petals to meet the sun's rays and turn to follow the sun throughout the day.

Here in a circle, one after another

Two girlfriends walk together.

Without pushing, without interfering

Big is moving fast (arrows)

In which watch can you see the hands?

The first mechanical watches appeared in Russia in the 15th century. It is curious that on the clock of that time, instead of numbers, letters were applied to the dial ... Watches can be wrist watches. They are worn on the arm using a bracelet or strap. Fashionistas like a beautiful watch in the form of a pendant or a ring. The pendant on a chain is put on the neck, and the ring is put on the finger. Some men prefer massive pocket watches. They are attached with a chain to a belt and carried in a trouser pocket.

You probably have a clock at home - an alarm clock.

Why do you need such a watch? - The alarm clock can be set at a certain hour, and with its bell or melody it will wake us up at the right time.

Like sentries on duty

The clock strides into darkness.

And their clear step is heard:

Tick-tock, tick-tock, tick-tock, tick-tock.

Take a look at your watch

Listen, are they coming?

The watch won't let you down

They are at any time

You will be told the time.

So that you don't oversleep your lesson

The clock will wake you up on time

At least hide your alarm clock

In the chest of drawers or in the refrigerator.

Hours are not given for beauty,

They dictate the time to us.

A person who can appreciate even a second can achieve a lot. Let's remember what famous people said about the time. Their sayings are in our magazine. (Guys come out with posters on which sayings are written).

"YOU CAN ALWAYS FIND ENOUGH TIME IF YOU USE IT WELL." (I. V. GOETHE).

“WHO IS NOT ABLE TO USE THEIR TIME WITHOUT, THE ONE COMPLAINS ABOUT HIS LACK OF TIME (J. LABREOYER)

"A careless person does everything doubly" ()

"They get tired and exhausted not so much because they work a lot, but because they do not work well" ()

Leading: We hope that these statements will make you think about time in a new way.

The watch does not stop for a second, time flows continuously. Let's listen in silence for a minute (includes chronometer)... See how long it is!

How much does one minute "cost"?

11. Organize your vacation wisely.

Teacher:

Our oral journal is finished, but the hours go on and life goes on. In adolescence, it seems endless, and many adolescents and young people put off their affairs for later. And suddenly one day they discover that most of their lives have already been lived. They did not manage to do what they wanted in life. They begin to justify themselves or blame others for it. But you yourself are to blame for this. They always sorely lacked time, because they preferred to spend it in front of the TV screen, computer monitor, aimless "walking" with friends, etc.

Leading: We will be glad if our oral journal made someone look at their own and others' time in a new way. We are sure that the advice will help you in preparing for the lessons, use your time wisely, and skillfully organize your rest.
